803939 ÷ 79 
Let's see how many times 79 fits into 803939.

Step 1:
79 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 79

Let's proceed to step 2:
80 divided by 79 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 79 from 80 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 79

Moving on to step 3:
79 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 79

Let's proceed to step 4:
If we divide 139 by 79, we get 1 and a remainder of 60.
The next digit of our result is 1. 
Result so far: 101.0
Subtract 79 from 139 to get 60.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 79

Advancing to step 5:
603 divided by 79 is 7 with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 1017.0
Subtract 553 from 603 to get 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 79

On to step 6:
79 can be fit into 509 6 times, resulting in a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 10176.0
Subtracting 474 from 509 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
79 can be fit into 350 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 10176.4
Deduct 316 from 350 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
340 divided by 79 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 10176.44
Deduct 316 from 340 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 10176.44 and a remainder of 0.024.
